Morsi, Have you heared about the sea of particles and antiparticles?! I adopt your way of thinking: Whatever was the sayings of the correct equations, TRUE LOGIC IS THE TRUE LOGIC. It is totally wrong to say that QED is built upon particles' creation or annihilation operators. And, I...

Oh! Thanks! But, HallsofIvy, let's talk, in special, in Minkoweski Space? I know that the latter is a physical concept, but, it refers to a special case which is 4 indices. What about transforming 4x4-Matrices (or Tensors, to be more precise), not only Vectors? But I have a question...

To get the effect of moving backward in time, on curvature; substitute with "-t" in equations instead of "t" in the Curvatur Tensor. To get the effect of moving backward in time, on gravity; substitute with "-t" in equations instead of "t" in the final free fall equations. Wonna add...

Harmony, Special relativity has been totally implied into QM (Previosity: Schroedinger) through Dirac's and KELIN-GORDON, for fermions and bosons respectively. Of course, Cesium, this was the case before Dirac's. But, there are still two problems in QM and also in QFT; a. can't deal with...

OOPS! The issue of quantum field theories is a puzzle for me till now. But, it is quite apparent that there is some differences in scientists' complete consideration for it. However many of them is talking about the theory as a total, but still away from the details. Why not and it was not...

Dear Fellows, Do anyone have an idea of whether there must be a system tensor in order to be able to transform from the covariant form of a certain tensor to its contravariant one? This is a bit important to get rigid basics about tensors. Schwartz Vandslire...

But Amr, Isn't it difficult for GR equations to give this simple result although being so complex and complicated. You are right most of specialized scientists say this fact except very few. But, thee some debates about this. What do you think? Is there more ideas about it? Is there other way...

Of Course Dexter, Lagrangian Form and Hamiltonian Form are different faces to the same Theory; QED. Schwartz Vandslire ------------------------------------------------ Either to work correctly as required, or to leave it.

Dexter, You are right. Dirac included SR in QM. The other 2 equations included Field Quantization (May be:{DUE TO QUNIZATION OF SOURCE CHARGES}). You can check them as much you can. But a question arises: What is the original? Is this form or the other or another one "if there is no...

Wrong! These equations have been absolutely believed of since feynmann... Thanks, to revise your knowledge about QFTs. Thanks ... and Brgrds. Nuclear Scientist!

Fellows, Of course... the concept of force is chaned in QM rather than classical mechanics.You are right anonym, but the wave function describes everything in that system even in the presence of many charges as it carries the probability for the particle to be at very small volume at some...

Hi, The following may work; http://scienceworld.wolfram.com/physics/QuantumElectrodynamics.html. It is simple but detailed and summed up. Doesn't it include the Dirac's Equation?! ------------------------------------------------ Either to work correctly as required, or to leave it.
